RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact electrical tolerances and packaging configuration. Ensure compatibility with standard die attachment methods such as eutectic solder or conductive epoxy. Confirm RoHS compliance status if required for the final assembly environment.

RF Diode Selection Notes

Select this component when high reverse voltage blocking is critical alongside low insertion loss. The 140 µm I-region offers a balance between switching speed and power handling capacity. Evaluate thermal dissipation requirements based on the specified thermal resistance value during continuous wave operation.

RF Diode Part Context

This part belongs to MACOM's Silicon PIN/NIP Diode Chips family, which utilizes ceramic glass and silicon nitride passivation technologies. The series covers various I-region lengths to optimize trade-offs between low capacitance, low series resistance, and high breakdown voltages for diverse control circuit needs.

RF Diode Replacement Considerations

Direct substitutes include other high-voltage Cermachip PIN diodes from the same manufacturer line, such as the MADP-011141-13160W or MA4P604-131, provided their voltage ratings and physical dimensions match the design constraints.
